(1) An error occurred during the maintenance assembly where the hammer blades were installed incorrectly. When replacing the hammer blades by flipping them over, all hammer blades within the shredder must be flipped over simultaneously to prevent the rotor from losing balance. Otherwise, a strong vibration may occur during operation.
(2) The weight difference between the two groups of hammer blades exceeds 5 grams. The solution is to adjust the weight of the hammer blades so that the weight difference between the corresponding groups is less than 5 grams.
(3) Some hammers are too tightly stuck, failing to dislodge during operation. After shutting down, manually rotate and inspect them, and find a way to make the hammers rotate more freely.
(4) The other parts on the shaft are unbalanced in weight; at this point, it is necessary to carefully inspect and adjust for balance individually.
(5) Spindle bending and deformation. The solution is to straighten or replace.
(6) Excessive bearing clearance or damage. Generally, replacing new bearings is required to resolve the issue.
(7) The bottom angle fixing nut is not properly tightened or may loosen during operation. The solution is to secure it properly.
